Hyaluronic acid, known as the "liquid gold" in the medical beauty world, is a substance naturally occurring in the human body. Its main function is to strongly moisturize and lock water. In the skin, it can absorb and maintain a large amount of water and maintain the skin. Full, soft and elastic, as you age, the hyaluronic acid content in the human body will decrease, leading to dry skin and wrinkles. In the field of medical beauty, by injecting hyaluronic acid fillers into the dermal layer or subcutaneous tissue of the skin, it can effectively improve fine lines, lips, Cheek-filling, filling of legal lines, nose augmentation, chin augmentation, etc., to achieve instant shaping and rejuvenation effects. As a common injection beauty method, hyaluronic acid products have a wide variety of products with a relatively high safety factor, but they still need to be made by professional doctors. Evaluate your choices based on your personal situation, pay attention to possible side effects and maintenance time, and understand the principle and application of hyaluronic acid, which will help you make more informed medical and aesthetic decisions.

What is hyaluronic acid?

玻尿酸，学名透明质酸（Hyaluronic Acid，简称HA），是一种天然存在于人体中的高分子多糖，它主要存在于皮肤、眼睛、关节等部位，具有强大的保湿和润滑功能，正是因为它出色的保水能力,玻尿酸在医美领域被广泛应用。

In the human body, the content of hyaluronic acid decreases with age. This is one of the reasons why we see that many people gradually lose elasticity and wrinkle as they age. Supplementing hyaluronic acid through medical and aesthetic means has become an important means for many people to delay aging and keep them young.

Types and uses of hyaluronic acid

Hyaluronic acid is not "one" product, but is divided into various types based on molecular weight, degree of crosslinking, purity, etc., and is suitable for different parts and effects.

Classification by molecular weight

• Polymer hyaluronic acid: Mainly used for deep filling, such as facial contour shaping, chin augmentation, etc., the effect is long-lasting but the liquidity is poor.

• Medium-molecular hyaluronic acid: Suitable for midface filling, lacrimal groove depression, etc., with both support and natural feeling.

• Low molecular weight hyaluronic acid: Mainly used to replenish water on the surface and dilute fine lines. It recovers quickly and is suitable for sensitive parts such as lips.

Classification by crosslinking technology

Cross-linking technology determines the hardness and durability of hyaluronic acid. The higher the degree of cross-linking, the stronger the supporting force of hyaluronic acid, but the metabolic rate will also slow down accordingly. Common types of cross-linking include:

• 未交联玻尿酸: Soft and natural, suitable for lips and other areas.

• single crosslinked hyaluronic acid：中等支撑力,适合初学者或浅层填充。

• 双重、三重交联玻尿酸: Strong support, suitable for deep filling, and the effect is more lasting.

用途广泛

• 面部填充: Filling lips, filling in decree lines, tear grooves, facial depressions, etc.

• injection except knit：淡化静态皱纹，如鱼尾纹、额头纹等。

• body contouring: Expand temples, chin, rejuvenate hands, etc.

• 关节润滑: Used for the treatment of osteoarthritis.

玻尿酸注射的安全性

As a non-permanent filler, hyaluronic acid injection is relatively safe under regular operation. Any medical beauty project has certain risks, and hyaluronic acid injection is no exception.

common side effects

• Red and swollen, bruise：注射后常见，通常1-3天可消退。

• 感染: If the operation is not standardized or postoperative care is improper, infection may occur.

• 过敏反应: Very few people are allergic to hyaluronic acid components, which manifest as rashes, itching, etc.

• 血管栓塞: If hyaluronic acid is injected into blood vessels, it may cause serious consequences and need to be avoided.

How to reduce risks?

• 选择正规机构: Be sure to take the injection in a qualified medical institution.

• Find a professional doctor: The doctor's technology and experience directly affect effectiveness and safety.

• 术前沟通: Clarify your needs and the doctor will recommend suitable hyaluronic acid products based on the facial structure.

• 术后护理: Avoid pressing and makeup, and follow doctor's advice to recover.

Precautions for hyaluronic acid injection

1. not as good as possible: The injection amount needs to be adjusted according to the personal facial foundation and needs. Excessive filling may cause facial rigidity.

2. 效果因人而异: The metabolic speed of hyaluronic acid is related to personal constitution and living habits, and the duration of the effect is usually 6-12 months.

3. Avoid frequent injections: After hyaluronic acid injection, the skin itself will gradually recover some functions, and frequent injections may affect the effect.

4. Postoperative dietary contraindications: Avoid spicy food such as seafood and spicy food for one week after injection to avoid affecting recovery.

The difference between hyaluronic acid and botulinum toxin

很多人对玻尿酸和肉毒素（肉毒杆菌素）分不清,其实两者是完全不同的产品：

• 玻尿酸: Filling products are mainly used to "fill" depressed areas, such as tear grooves, decree lines, etc.

• 肉毒素: Relaxation products are mainly used to "relax" muscles, such as eyebrow lines, crow's feet, etc.

Hyaluronic acid is "filled in" and Botox is "released". The two can complement each other, but they need to be comprehensively judged by a professional doctor based on the facial condition.

玻尿酸的未来发展趋势

随着科技的发展,玻尿酸也在不断升级：

• degradable hyaluronic acid: It is more in line with the human body's natural metabolism and reduces side effects.

• 多功能玻尿酸: It has multiple functions such as filling, anti-aging, and repair.

• Bioactive hyaluronic acid：不仅能填充，还能促进collagen regeneration,效果更自然。

Hyaluronic acid will develop in a safer, more natural and more lasting direction.
